How plastic can be used for road construction purpose,explain?
“The plastic waste, creating pollution hazards all over the country, can be turned into an ‘’environment- friendly’’ purpose if used in the construction of roads, according to a study sponsored by the Central Pollution Control Board. Bitumen blended with waste polymers such as polythylene (sheets), polypropylene (sheet and film) and Polystrene (thermocol) has improved properties as binder for the road construction, experiments done by Thiagaraj College of Engineering, Madurai, have proved. Use of shredded plastic waste in bitumen for laying roads has helped in preventing creation of potholes, a common problem of Indian roads. The technology is eco-friendly too as re-use of the plastic waste in this method is better than recycling of the material, which emits fugitive emissions. Problems like disposal of waste and blockages of waste stream would be automatically taken care of once its put to use. Under the existing method, granite mixture is used with bitumen. The blend cannot prevent t
